Nokia Research and the European Research Council are funding the University of Sussex towards the development of smart hands technology.
The British scientists have managed to turn the human hand into a touchscreen, with the aid of a specialized device which emits ultrasounds. This innovation is called SkinHaptics and uses time-reversal processing in order to transmiit ultrasonic waves. This technique essentially works like ripples in the water, but in reverse; the waves become more focused as they are transmitted onto the hand, reaching a certain point on the palm. This gives the user the ability to control a smartphone or any other smart-wearable device.
